2013 Audi A4 2.0L Diesel · AD13 AOD

The vehicle is currently roadworthy but the maintenance trend shows a clear shift towards worsening mechanical neglect. While the most recent test in May 2026 at 104,792 miles passed, it revealed three significant defects that were not present in previous years. The tester flagged an offside front wheel bearing with play, a severely deteriorated offside front drive shaft CV boot, and front inner tyres worn to the limit on both sides. These issues indicate that while the car remains legal, the preventative maintenance of wear components is being deferred. The mileage pattern is consistent with a thirteen-year-old German saloon, averaging approximately 8,000 miles per year. The record shows a stable history between 2016 and 2023, where the vehicle frequently passed with no defects. However, mileage accumulation accelerated slightly after 2023, with over 12,000 miles covered between the October 2023 and May 2026 tests. Appearance of the CV boot fault in 2024 and its persistence into 2026 suggests a failure to address a minor issue before it reached a critical state. A buyer must inspect the front suspension and drivetrain thoroughly due to the recurring faults. The play in the offside front wheel bearing requires immediate replacement to prevent catastrophic failure, and the deteriorated CV boot likely leads to grease loss and eventual joint failure. The uneven wear on the inner edges of both front tyres strongly suggests a persistent alignment issue or worn suspension bushes that need to be diagnosed by a technician. Check for signs of oil leakage around the drive shaft, as the history indicates this component has been failing for two years.
